Speech, Tongue Posture, and Bite Problems in Children

Children with crooked bites often also have trouble with certain speech sounds, and many rest their tongues low in the mouth or swallow in an unusual way. This systematic review set out to clarify whether these things genuinely travel together, examining the relationships between orofacial myofunctional disorders, articulation disorders, and malocclusions in children and adolescents aged roughly 3 and up.

The myofunctional disorders under study — a low resting tongue posture, deviant swallowing, bruxism, and biting habits — all involve how the soft tissues of the mouth behave at rest and in motion. Because these are common in childhood, untangling how they relate to both speech and bite was the review's central aim.

This matters because it bridges disciplines that rarely talk: dentistry, speech therapy, and orofacial myofunctional therapy. A child sent to a speech therapist for a lisp and to an orthodontist for crowding may be showing two faces of the same underlying tongue dysfunction. Seeing the connection is what makes it possible to treat the cause rather than chase the symptoms separately.
